Creature Access Doors are doors in Spyro: Year of the Dragon that are closed when the other playable characters, Sheila, Sgt. Byrd, Bentley and Agent 9, aren't freed. These doors will have a bad sign and access will be denied. Although these are part of the realm geometry and not standalone objects, Spyro must unlock the challenges in order to get through and the doors will be placed underground. For some of the realms, Spyro can use a glitch to get in the entrance quickly as possible without rescuing them. The only areas that Spyro cannot circumvent are Enchanted Towers, Charmed Ridge, Desert Ruins (where the door is misplaced and never used to block Spyro from entering unless that would be placed at the entrance) and Haunted Tomb. They may have an extra piece of wood.
